Melbourne: Match-fixing is commonplace in tennis' lower levels and efforts to fight it are inadequate, a senior anti-corruption official said after cheating claims rocked the sport during the Australian Open.

The controversy is just the latest to hit the tainted sports world after claims of a doping cover-up shook athletics and multiple scandals engulfed football's governing body, FIFA.

Eaton, directory of integrity at the ICSS, said professional betting analysis showed 'nil manipulation' of matches at the top levels of tennis where players are highly paid and less susceptible to bribery.
